John Doyle Lee (September 6, 1812 – March 23, 1877) was an American pioneer, and prominent early member of the Latter Day Saint Movement in Utah. Lee was later excommunicated from the Church and convicted of mass murder for his complicity in the 1857 Mountain Meadows Massacre. He was sentenced to death and, in 1877, was executed by firing squad at the site of the massacre. Provided by Wikipedia
